What would happen if a Quad Bike mated with a Jet Ski?… You’d get the The Gibbs Technology Quadski, the first commercially viable, high-speed Quad Bike/ATV and Jet Ski all in one.

The Quadski’s amphibian design offers a new class of recreational vehicle; powered by a 140-horsepower gasoline engine on land and a marine jet pump on water, the Quadski is capable of reaching speeds of 50 mph on land as well as sea.

The transition from one medium to the other takes less than five seconds. On entering water, the wheels are retracted into the body of the vehicle with the flick of a switch.

Quadski’s fuel tank allows it to travel for up to two hours on water and has a land range of about 373 miles (600 km.)

While the Quadski may seem like the ultimate Rich Man’s water-toy, Gibbs Technologies says it was actually designed with a more utilitarian purpose in mind. It’s unique amphibian abilities make it ideal for search and rescue, military, emergency services and aid workers who will be able to reach areas and people no two or four wheel drive vehicle could reach.

The Quadski shares technology with the recently launched Aquada, an amphibian car that set a world record for crossing the English Channel, and the Humdinga, a five-seat, four-wheel-drive military-style vehicle that can travel up to 80 mph on land and 45 mph on water.

For you skeptics out there who think this sounds like – “just another one of those cool concept vehicles that never come to fruition” – check out the movie below. The Quadski goes into production sometime in early 2009.
